Exhausted, scared, emotional as EDD approaches

Hi Mummies/Mums-to-be, recently I've been feeling down due to many reasons (pregnancy, work, everything). Experiencing pain and discomfort in lower back, pelvic etc. Feels nauseous/gagging at times.. My husband isn't the best emotional support pillar and I just feel so exhausted, overwhelmed as my EDD is approaching in Nov. I feel like there's so many unknowns and I feel so alone :( What are some tips that help may help to cope? Thanks in advance
